When I was a little kid, Halloween seemed like the most grown-up holiday of all. For one thrilling night of the year, I got to stay up late trick-or-treating, watch scary movies with my friends, and wield sharp and pointy objects (safety first, of course!) while carving a macabre face into a pumpkin.

Now that I'm older, my perspective on Halloween has shifted a bit. It’s now the holiday that most celebrates a childlike sense of wonder and amazement. Ordinary people and places are temporarily transformed into creepy and whimsical versions of their former selves: a zombie rises with the aid of corn syrup and some red food coloring, your everyday home becomes a haunted house with eerie lights and a spooky soundtrack, and a pumpkin—an otherwise plain-looking squash—is a grinning ghoul, with the help of only a candle, a knife and some elbow grease.

To celebrate Halloween this year, the doodle team wanted to capture that fascinating transformation that takes place when carving a pumpkin. Instead of picking up a few pumpkins from the grocery store, however, we decided to work on six giant pumpkins, specially delivered from nearby Half Moon Bay (some weighing well over 1,000 pounds). What you see is a timelapse video of the approximately eight hours we spent carving in the middle of our Mountain View, Calif. campus.

Googlers got into the Halloween spirit as well—you can see their costumed cameos if you have a quick eye. Many thanks to Slavic Soul Party! and composer Matt Moran for providing a fitting soundtrack for our Halloween hijinks.

From all of us at Google, take care, be safe and have fun this Halloween!
